I have an app that allows users to select items from a ComboBox, click a FlexGrid and the item in the ComboBox apperars in the FlexGrid.

Works great.

Users have asked for an Undo feature.

I've thrown up my hands and yelled "I don't know how to do that!" but they insist.

Anyone have any pointers on how to implement Undo on the FlexGrid?

Thanks!
